Specification forming part of Letters Patent N o. l 86,456, datedJanuary 23, 1877; 4application filed May 11, 1876.

To all whom it may concern: y

Be it known that I, WILLIAM S. LUsooMB,

of the city and county of Providence, and

State of Rhode Island, have invented a new and useful Improvementin'Bolster and Steps of Spinning-Machines, which improvement ishereinafter set forth in the following specification, reference beinghad to thel accompanying drawings.

The object of my invention is to obtain a spindle which will not beaffected byl the settling of buildings or floors, but which will retainitsoiiginal position as iirst set in motion ready for operation,unaffected by any causes which would change the level or plane of thefloor onwhich the machinery is placed. This object isattained by meansof a receiver connected with the spihdle, as will hereinafter bedescribed. Another object is abetter mode of oiling the spindle than atpresent has been attained.

Figure 1 is a vertical section of the spindle with the 'severalimprovements connected therewith. f

A represents the live spindle; B, the-receiver; C, the spindle-bolster;D, the spindle-step. E is the step or support to the receiver B,hereinafter called the receiver-step.77 F F are the rails. Gr is thescrew for securing the receiver-supportv E to the lower rail F. H H arethe caps to the oil-receptacles L L.

` The oil-receptacles are the spindle-holsters C and spindle-step D,cupped out for that purpose. I I are oil-conductors used inspindlebolster Gand spindle-step D, which hold the oil. Theseoilconductors may be made of metal, or of any material which, byvibration, will cause the oil to flow along the surface of the materialfrom `the source or fountain of supply. J J are holes or openingsthrough the spindle-bolster C and spindle-step D, next to the spindle A,through which openings the points of oil-conductors I I penetrate justfar enough to come in slight contact with spindle A, so that when thespindle is in motion, the oil-conductors I I will vibrate by the touch,and by this vibration the oil in theOil-receptacles ilows slowly upalong these oil-conductors I l toward their points of contact with thespindle, thereby constantly feeding it with the oil. I have chosen tomake these oil-conductsuch process. v absorbed or pressed out, but, onthe contrary,

I do not limit my invention to that form,

neither to any metallic substance which I have preferred to use in thisform.

I am aware that spindles are oiled by the use of absorbents, and make noclaim to any By my iuven tion the oil is not the method devised feedsthe spindle by the transmission of the oil over the exteral surface ofthe material used for such transmission. I claim for this mode of oilinga utility and superiority over existing methods, because it avoids thecollection of dust, particles of matter, and inorusting of theabsorbents which result after a time from the use of absorbents, andwhich necessarily, unless frequently replaced, are communicated to thespindle, to its injury. By this vibration, caused by the contact ci' theprojecting points of' these oilconductors I I through the openings J J,these openings are kept clear from the-collection of foreign materials,as they are to be made small enough and only large enough for the freevibration of these projecting points when in conj tact with the spindlein operation, and for the oil so owing along the surface of theseconductors to get to these points.

K is the collar to keep the spindle from rising at dofing. M, in Figs. land 4, is to represent an open passage through the lower extremity ofthe spindle-step D, beginningat v l Throiigh one side of `the center of`the step. this open passage the refuse oil upon the spindle can passoff, instead of collecting around `and about the step of the spindle.

Fig. 2-is a front elevation of receiver B. Fig. 3 is the spindle-bolsterO. Fig. 4 is the spindle-step D. l

The lower extremity of spindle-bolster C, through which the spindle Apasses, is tapered, so as to fit so closely into the upper extremity ofreceiver B as to be held firmly by the latter. is adjusted in its shapeto` hold securely the tapered spindle-bolster C. The lower extremity isso formed at its upper part as to receive and hold rmly in its placeinterior to it the spindle-step D, as shown in the drawing. The lowerpart or base of the lower extremity of The upper extremity of receiver Breceiver B may be a ballfjoint, or of any other shape or form which willenable it to adjust itself to any irregularities of the rail F from anycause When the receiver rests upon the step or support E. This receiverstep or support E is connected with the screw G, which secures it to thelower rail F, and is so adapted at its point of contact with the-lowerextremity of receiver B as to enable the vreceiver to movein or u ponthe support- E, so that any strain or irregularity will be felt by andaffect the adjustable receiver B, and not the spindle A. I have made thepart of the receiver B Where it comes in contact with the receiverstep Erounding; but it may be made in any other shape which will readily1adjust yit to the position of the receiver-step.

What I claim, and desire t0 secure by Letters Patent, is-

1. The spindle A, in combination with the spindlebolster C, the receiverB, the spindlestep D, the receiver step or support E, and the rails F F,substantially as described.

2. The receiver B, in combination with receiver-step E and rails F F,substantially as described.

3. In combination with a rotating spindle and a bolster or step,provided with an oil-receptacle and an interior sleeve having aperforation, as described, a flexible oil-conductor extending fromWithin the oil-receptacle through the perforation to and bearing againstthe spindle, whereby, when the latter is in motion, the said conductor-Will be caused to vibrate, and thus feed oil to the spindle-bearings, aset forth. y
